Analogue CMOS high-frequency continuouswavelet transform circuit

A 16-channel analogue CMOS high-frequency continuous wavelet transform circuit has been realised. The circuit performs a time-frequency decomposition of a high-frequency input signal. A 100 MHz operating frequency, 45 MHz bandwidth, and 40 mW/channel power dissipation have been achieved using a 0.5 µm CMOS process.
